The person wants honest advise from car users. I presume he will not be using it for drag racing.
I have driven all the Civic's since 2006 (all 3-generations). I personally liked 2006, for its smooth ride and engine performance.
My 2006 Reborn had stiffer suspension which was not to my liking especially in the city with patches & pot holed roads, engine was silky smooth all the way.
My new 2012 Civic is a redefined Reborn, especially like the quite interior and the climate control.
I bought 2010 Altis 1.8 Cruisetronic for Cruise control & Tiptronic gearbox.
Altis is a class in its own, very smooth suspension, quite interior.
My sincere advise is that you drive both these cars before making any decision.
